I've a matched pair of United NOS 805 tubes. They are made by GE. I used it on a Line Magnetic LM 508ia for less than 100 hours. I will include the top cap wires at my asking price.
Buyers pay $249 + shipping (from 11106) and paypal fee.
P.S. I also have a few additional set of 6SL7 and 6SN7 tubes that are proved to work great with LM 508ia and takes it to a new height. As, I've sold the 508ia, I've no use for those. If interested, PM me.
